Patented May as, rear.

Application filed June 29, 1915. Serial No. 37,109.

To all whom it may concern:

Be it known that 1, ROBERT RUssnLL SYMONS, a citizen of the United States, residing at Dodgeville, in the county of Iowa and State of Wisconsin, have invented cer tain new and useful Improvements in Penholders, of which the following is specification.

My invention relates to pen holders, and more particularly to that class of pen holders known as releasing pen holders.

The primary object of my invention is to provide a pen holder of the class above described which is simple in construction, cheap to manufacture. strong and durable, and effective in operation.

Another object of my invention is to provide a pen holder of the class above described which frictionally retains a pen by means of an improved clamping jaw.

A further object of my invention is to provide improved releasing means for said clamping jaw.

With the above and other objects in view my invention resides preferably in the construction, combination, and arrangement of parts as hereinafter set forth in the specification and illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal sectional view' of a pen holder embodying the improvements of my invention showing the same with a pen clamped therein.

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a similar view taken on the line 3-3 of Fig. 1.

Fig. 4 is a similar view to Fig. 3 taken on the line 4-4 of Fig. 1.

Fig. 5 is a detail plan view of the improved clamping jaw.

Fig. 6 is a detail enlarged perspective view of a portion of the releasing means.

Similar reference characters indicate similar parts throughout the various views of the drawings.

In the drawings, wherein is illustrated the preferred embodiment of my mvention a pen holding shank is designated 1, said shank being preferably tubular and having a finger gripping portion of cork or the like 2 placed on the outer periphery thereof. A handle 3 is shown secured to the shank 1 by means of a rivet 4 or the like. The shank 1 is provided at a point substantially intermediate its length with an ins antly struck portion providing a loop 5 for a pur pose which will hereinafter appear. The shank is also provided with an aperture 6 for a purpose which will hereinafter appear, the aperture 6 extending through the cork outer lining 2, as shown to advantage in Figs. 1 and 4.

The clamping means of my invention includes a strip 7 of resilient metal, said strip 7 being enlarged as at 8 adjacent one eX- tremity and bifurcated at 9 to provide a yielding clamping jaw. The strip 7 is preferably offset as at 7 in order to space the clamping jaw a slight distance from the inner periphery of the shank 1. The opposite extremity of the strip 7 is riveted or otherwise secured to the inner periphery of the shank l, as indicated at 10, and shown to advantage in Fig. 1. The clamping portion 8 is provided with a hook 11 for a purpose which will hereinafter appear. As shown to advantage in Fig. 1, the clamping portion 8 of the strip 7 is adapted to extend beyond the outer terminal of the shank 1 so as to facilitate the insertion and assure the retention of a pen 12.

The releasing means of my invention includes a bearing pin 13, said bearing pin being extended transversely of the shank 1 and secured at points substantially diametrically opposite. A bell crank lever 14; is j ournaled on the pin 13 and is provided with arms 15 and 16. The arm 16 is preferably greater in length than the arm 15 for a purpose which will hereinafter appear. A link 17 serves to connect the apertured end of the arm 15 with the hook 11 carried by the clamping portion 8. The free apertured eX- tremity of the arm 16 is connected to an operating rod 18, said rod 18 being slidably mounted in the guiding loop 5, as indicated to advantage in Figs. 1 and 3. The free extremity of the operating rod 18 is bent to provide a fingenengaging portion 19 projecting through the elongated aperture 6 and beyond the outer periphery of the lining 2.

In operation, pressure is exerted on the finger-engaging portion 19 of the operating rod 18 to move the same to the rear extremity of the elongated aperture 6. By virtue of the fact that the arm 16 is longer than the arm 15 of the bell crank lever, the pressure exerted on the finger-engaging portion 19 will be comparatively slight to move the jaw o released position. This will direct a pull:

011 the bell crank lever 14 through the arm 16, causing the arm 15 of the bell crank lever to draw the clamping portion 8 away from the pen and allow the removal of the latter. It will be noted that the bifurcated clamping portion 8, by virtue of its bifurcation, permits the same to accommodate itself to different sizes of pens, that is, pens being of different curvature in cross section.

From the above description taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation, and advantages of my invention can be readily gathered, and it is to be understood that while I have shown my inven tion as embodying a specified structure, certain changes may be made in the details thereof which do not depart from the spirit and scope of the invention as claimed.

What is claimed is:

1. A releasing pen holder, including a tubular shank, a clamping member, said clamping member comprising a single piece Copies of this patent may be obtained for of spring metal offset intermediate its length, a bell crank lever, means connected withsaid bell crank lever to the clamping member, and actuating means for said lever. v

2. A releasing pen holder, including a tubular shank, a pen clamping and retaining member arranged within said shank and formed from a single piece of spring metal otlset intermediate its length, a bell crank lever pivotally mounted interiorly of the shank and connected with the free end of said clamping and retaining member, and a slidable operating rod connected with the remaining end 01' the bell crank lever and extending exteriorly of the shank, whereby, the clamping and retaining member can be disengaged from a pen.

In testimony whereof I atiiX my signature in presence of two witnesses.
